Answer: 
Yes, easily. And since 5 gallons is 90 lb of concrete, you only need 1 90 lb bag.

This product is often used to set fence posts, and it is typically recommended to set 1/3 of the total length of the post in the ground.

If this is being used to set a horseshoe stake to establish a horseshoe pit, you may consider digging a hole into which you insert an appropriately cut portion of a QUIK-TUBE, with the top being at ground level, which can serve as a form for pouring the QUIKRETE Fast Setting Concrete Mix.

Answer: 
Yes, but the bucket will crack and not last as long as the concrete and stake. Lifting the bucket with its handle after the concrete is hard may be a bit heavier than you think. So if you want it to be portable or something, you will eventually just have to grab it by the stake or the concrete to move it around.

Answer: 
I don't know why not. Considering the volume of a five gallon bucket, you would probably need 2 bags of quickcrete. You might want to also drill some holes in the stake and put something like a rod or bolt through to keep the pole from coming out of the concrete.

For a thickness of 1/2-1 inch, you can use QUIKRETE Sand Topping Mix blended with QUIKRETE Concrete Acrylic Fortifier #8610 replacing a portion of the mixing water. Do not utilize the Concrete Bonding Adhesive in the same job application as the Concrete Acrylic Fortifier. Read Less

Answer: 
No, not without help. You will need to look for a bottle of concrete bonding adhesive or bonding agent. I've done this before, but the recommendation is to use a thinner setting concrete. Read the labels and find the concretes that say they are for thin, tapered slabs, like down to 1/4 inch. Those will have almost no aggregate and they are expensive in large quantities. Might want to hire someone.

I have used this produce in the same type of weather to make support blocks 16x24x8 above ground--But I protected it from freezing overnight with the use of insulation blankets. No harm seemed to be done to the blocks--but you are taking a chance.--If it freezes before it cures and the moisture is out it will crack.

Answer: 
YES, definitely YES! This type of concrete has accelerators and it will do well because of the self-heating aspect of it. Do not dilute it in cold weather with regular concrete. Use it just as the instructions on the bag say. Don't get it too wet. You could substitute hot water for cold water and it will help a little.

Yes - However, in cold weather, which, for the purposes of concreting, may be considered to be weather that is below 50 dF, or near freezing 32 dF at night, it is important to take certain precautions: 1) Mix the concrete with water before placing the material in the hole, 2) store the bagged concrete in a warm temperature before use, and use warm water to mix, 3) protect the concrete from freezing for at least 48 hours for QUIKRETE Fast Setting Concrete Mix using plastic sheeting, insulated blankets, or other means. If these preventive measures cannot be taken, it would be best to wait for warmer weather. In weather above 50 dF, if pouring the QUIKRETE Fast Setting Concrete Mix into the hole dry, place the material in lifts of 2' 6” or less, adding the appropriate amount of water for each lift, to allow water to soak all the way through. Using a shovel to “chop” the material in the hole will help distribute the water. Read Less

Rated 4.3 out of 5 by 49 reviewers.
Rated 5.0 out of 5.0 by Worksaver - sets hard without mixing, just pour concrete in the hole and add water, holds my post strong This concrete saves the time and effort of mixing. Just pour the concrete in the hole and spray on some water. Sets very fast and provides a strong hold for my post. It is only a 50 pound bag, so you are paying for convenience but very worth it if you are installing just 1 or 2 posts. October 11, 2016
Rated 5.0 out of 5.0 by easy to use! Excellent! Used the estimator for how many bags I would need for the small project - way off - only needed 1 bag and the estimator gave me 6 to purchase; so I had to return 5. October 11, 2016
Rated 4.0 out of 5.0 by good product used to set fence post for chain link fence worked as advertised Used to set fence post for chain link fence worked as advertised / not the best price for what it is. October 5, 2016
Rated 5.0 out of 5.0 by Works well I have used this product before and it worked just as well this time. I'm a small woman so the difference between a 50lb bag and 80lb bag makes a difference. Also I don't have to premix which also takes a lot of physical strength. I do pour it in the hole pour in the right amount of water and use a piece of rebar to make sure the water mixes well with the concrete mix all through. I put up a chain link fence oh maybe 10 years ago. No sign of any cracks all standing well. Doing better than the concrete where the fence builder I paid to put up the privacy fence put in his post holes. August 23, 2016
